“…Research regarding NO 3 − transport in the vadose zone has been conducted in agricultural settings under various irrigation practices, such as drip (Baram et al, 2016;Lv et al, 2019;Phogat et al, 2014), sprinkler (Baram et al, 2016;Gheysari et al, 2009), and flood irrigation (Di & Cameron, 2002a;Wang et al, 2010). These studies have concluded that N supply from the vadose zone to the groundwater is transport limited rather than source limited, with the most efficient irrigation systems (drip and sprinkler) leaching lower amounts of NO 3 − from the soil profile.…”

“…Wang et al (2010) flooded a winter wheat (Triticum aestivum L.)summer maize (Zea mays L.) cropping systems on a silt loam soil in the North China Plain every 72 h with two 25-cm water applications and found that 62 ± 7% of the NO 3 − within the upper 200 cm of the soil profile was leached. Lv et al (2019) reported that flood irrigation of tomato (Solanum lycopersicum L.) fields in a silt loam at an agricultural experimental station in Tianjin City, China, showed low N use efficiency resulting in 50% of total N input being leached (300 kg N ha −1…”

Agricultural managed aquifer recharge (Ag-MAR) is a concept in which farmland is flooded during the winter using excess surface water to recharge the underlying groundwater. In this study, we show how different recharge practices affect NO 3 − leaching and mineralization-denitrification processes in different soil systems. Two contrasting soil textures (sand and fine sandy loam) from the Central Valley, California, were repeatedly flooded with 15 cm of water at varying time intervals in field and soil column experiments. Nitrogen species (NO 3 -, NH 4 + , total N), total C, dissolved O 2 , and moisture content were measured throughout the experiments. Results show that when flooding occurs at longer intervals (every 1-2 wk), N mineralization increases, leading to an increase of mobile NO 3 − in the upper root zone and leaching of significant quantities of NO 3 − from both soil textures (137.3 ± 6.6% [sand] and 145.7 ± 5.8% [fine sandy loam] of initial residual soil NO 3 − ) during subsequent flooding events. Laboratory mineralization incubations show that long flooding intervals promote mineralization and production of excess NO 3 − at rates of 0.11-3.93 mg N kg -1 wk -1 (sand) and 0.08-3.41 mg N kg -1 wk -1 (fine sandy loam). Decreasing the flooding frequency to 72 h reduces potential mineralization, decreasing the amount of NO 3 − leached during flooding events (31.7 ± 3.8% [sand] and 64.7 ± 10.4% [fine sandy loam] of initial residual soil NO 3 -). The results indicate that implementing recharge as repeated events over a long (multiple-week) time horizon might increase the total amount of NO 3 − potentially available for leaching to groundwater. INTRODUCTIONDependence on groundwater for irrigation and consumptive use has resulted in the widespread depletion of groundwater aquifers across the world (Dalin et al., 2019;Wada et al.,

“…Farmers typically apply nitrogen (N) fertilizer (synthetic and manure) in two cropping seasons per year at rates that exceed plant requirements by a factor of 4 -5, amounting to >2000 kg N ha −1 yr −1 (Fan et al 2014;Yang et al 2016). Moreover, traditional flood irrigation is usually used, which is up to 1200-1600 mm per year and is 2-3 times higher than plant demand (Lv et al 2019). This practice promotes high N leaching losses, resulting in the contamination of groundwater with nitrate (Lv et al 2019;Qasim et al 2021;Zhu et al 2005), and leading to major health risks for the local population.…”

Background About 30 % of vegetables in China are produced in intensively managed greenhouses comprising flood irrigation and extreme rates of nitrogen fertilizers. Little is known about denitrification N losses. Methods Soil denitrification rates were measured by the acetylene inhibition technique applied to anaerobically incubated soil samples. Four different greenhouse management systems were differentiated: Conventional flood irrigation and over-fertilization (CIF, 800 kg N ha−1, 460 mm); CIF plus straw incorporation (CIF+S, 889 kg N ha−1, 460 mm); Drip fertigation with reduced fertilizer application rates (DIF, 314 kg N ha−1, 190 mm); DIF plus straw incorporation (DIF+S, 403 kg N ha−1, 190 mm). Soil denitrification was measured on nine sampling dates during the growing season (Feb 2019-May 2019) for the top-/ subsoil (0 – 20/ 20- 40 cm) and on three sampling dates for deep soils (40-60/ 80-100 cm). Data was used to constrain N-input-output balances of the different vegetable production systems. Results Rates of denitrification were at least one magnitude higher in topsoil than in sub- and deep soils. Total seasonal denitrification N losses for the 0 – 40 cm soil layer ranged from 76 (DIF) to 422 kg N ha−1 (CIF+S). Straw addition stimulated soil denitrification in top- and subsoil, but not in deep soil layers. Integrating our denitrification data (0-100 cm) with additional data on N leaching, N2O emissions, plant N uptake, and NH3 volatilization showed, that on average 50 % of added N fertilizers are lost due to denitrification. Conclusions Denitrification is likely the dominant environmental N loss pathway in greenhouse vegetable production systems. Reducing irrigation and fertilizer application rates while incorporating straw in soils allows the reduction of accumulated nitrate.
